An optical fiber connector socket for ignition and detonation

Abstract

The invention relates to an optical fiber connector socket for ignition and detonation. The optical fiber connector socket for ignition and detonation comprises a hollow socket shell, and the front end of the socket shell forms a butt end for plugging with a matching optical fiber connector plug , the rear end of the socket housing forms a connection end for connecting the detonator, the socket housing is provided with a pin component, and the pin component includes a pin structure for receiving the optical signal output by the optical fiber connector plug and detonating the detonator , the pin component also includes a pin fixing piece inserted in the socket housing and positioned by the rear and forward stop, the pin fixing piece has a welding connection part welded and sealed with the socket housing, the pin fixing piece and the socket housing are welded and sealed. A peripheral surface sealing structure is provided between the socket housings on the side of the welded connection portion in the front-rear direction. The optical fiber connector socket for ignition and detonation is double-sealed to ensure its own sealing effect under the action of a relatively large impact force.

Description

technical field [0001] The invention relates to the field of optical fiber connectors, in particular to an optical fiber connector socket for ignition and detonation. Background technique [0002] With the rapid development of optical fiber transmission technology, the function of optical fiber connectors has become more and more powerful, and its application range has become wider and wider. For example, in environments that require high-power laser transmission (such as laser ignition systems in aerospace systems), optical fibers are used. Connector. At present, the optical fiber connectors used in laser ignition technology are mainly ST or FC optical fiber connectors. Taking the ignition system using ST type optical fiber connectors as an example, the working principle is as follows: place the powder box and the optical fiber connector on the At the ignition position of the engine, the ignition laser beam shoots out from the front end of the pin of the optical fiber conn...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an optical fiber connector socket for ignition and detonation with better sealing performance, so as to solve the problem of the optical fiber connector under the action of a relatively large impact force when only relying on the welding and sealing of the pin part and the socket housing in the prior art. The socket is prone to technical problems of seal failure
